No you don't want to trim leaves.

Those are the solar panels for those future bud sites. Cut those and you get no bud secondaries.

You can 'fold' the leaves back or 'tuck' them...but really...the buds will form if you have strong enuff light to penetrate.

I always want strong light penetration and those secondaries will form.

Its is critical that you not cut them.

If you need more light get more light. Just dont ever cut those fans....ever....
